I guess funding a centralized payment system first wouldn't be any worse in this case. I guess it's not that easy to implement a system like the one you're suggesting. I don't see why we would want to use Bitcoin in this case?

It would be really cool. You wouldn't have to worry about getting an Ezpass and loading that up as long as you have some Bitcoins in your wallet .

Yeah, you only need to wait 10 minutes at the booth for the transaction to confirm

Most merchants (toll road likely included) can safely accept a 0/unconfirmed transaction for smaller amounts as it costs a lot to attempt a double spend attack and these attacks only have a positive EV with larger amounts as they do not always succeed.
